Bollocknaked Sauce

This is a variant of the classic 'Bolognese' meat sauce, for which there are as many versions as there are cooks (especially grumpy 'Italian' matriarchs, perpetually dressed in Mourning, and provocatively opinionated).
Anyhoo, it's important that the essence of this recipe rests on the tomatoes, onions, garlic, oregano, meat and olive oil; all the rest is just showing off.
So the jalapenos, ginger and such are there to lend a subtle zip to the flavour.
Incidentally, 'Bollocknaked' is English English for totally nude. This is irrelevant; it's just a naughty word that sounds like Bolognese.

In a 10 qt. (2.5 USgall; 2 UKgall; 9.5 l) jam pan (or similar large stove-top cauldron), get the olive oil just sizzling on a medium-high heat, and fry the onions, peppers, celery, garlic, ginger and oregano. Stir well at first, then occasionally enough to make the frying even.
SAFETY: DO NOT LET THE OIL GET HOT ENOUGH TO CATCH FIRE!

While the veggies are softening, add a cup of the pasta sauce (ragu) to the ground beef in a bowl, and manually squidge them together so that the meat is well broken up and should avoid clumping together in big lumps when cooking.

3

When the veggies have just softened, add the meat mixture and stir well.
Cook further until it looks like the meat is no longer raw.

4

Dump in the remaining pasta sauce, the lime zest and the tomato paste.
Put the lime juice and Worcestershire sauce in the pasta sauce jar and fix the cap on. Shake the liquid vigorously to rinse the pasta sauce off the jar, then thoroughly drain this mixture into cooking vessel and stir well.

5

Bring the meat sauce to a boil for 5 minutes while stirring constantly, then reduce the heat to simmer gently uncovered for 1 1/2 - 2 hours. The sauce should have reduced nicely.
Stir occasionally to prevent sticking and burning.

6

Use in any variety of pasta dishes; serve over rice or chips (or fries if you're not English); as a topping for hot dogs, or alternative filling for sloppy joes; blend 'til fairly smooth in a food processor and use as pizza sauce, or even as base for soup.
Don't forget to provide grated parmesan for those who think it's obligatory; also the garlic bread or warmed pita bread brushed with herbed olive oil.
A glass or two of a decent Valpolicella red probably wouldn't go amiss.

I usually make a batch this big to split into 2-cup portions for freezing for future meals.
